OBJECTIVE: To probe into the cognition of the elderly to the safety of drug use and their demand for pharmaceutical care,and to improve pharmaceutical care in the hospital and guarantee the safety of drug use.METHODS: Questionnaires about medication information were designed.315 elderly patients,who were collected from 10 old-age homes of Liaocheng,domestic sickbed department and 5 community medical service stations of Liaocheng Municipal People's Hospital from Oct.2008 to Mar.2009,were involved in study.Investigation data were analyzed statistically using SPSS17.0 software.RESULTS & CONCLUSIONS: Results of study showed that the elderly had not sufficient knowledge towards the safety of drug use,especially drug allergies,side effects of drugs and special population medication.There was significant difference in the understanding of the safety of drug use among the elderly with different education levels,different occupations and different medical insurance patterns.The potential danger of medication is present.They are desirous of acquiring pharmaceutical care.Pharmacists should carry out medicine consultation and popularize pharmaceutical knowledge.They also should provide a comprehensive pharmaceutical care for the elderly people to ensure the safety of drug use in the elderly.

Immunoblotting(IB) technique has been frequently used to detect bullous pemphigoid (BP) antibodies in BP patient.It is important to extract the antigen proteins fully and intactly in the base membrane zone(BMZ) of normal human epidermis.The simple method of extracting antigens will make IB techniqne easy.Three different methods of extracting antigen proteins were compared.Using IB for detecting BP antibodies,it has been found that the results of epidermal extract preparations are basically similar.However,one of these methods (NO.1) is more convenient and may obtain more amounts of antigens.Another method(No.3) is identical to that of extracting antigens in dermis for de- tecting epidermolysis bullosa acquista (EBA) antibodies.Therefore,in using IB technique to distinguish BP from EBA,one can apply method No.3.

The problem based teaching (PBT) has been the main approach to the training in the universities o the world. Combined with the team oriented learning method, PBT will become the method available to the education in medical universities. In the paper, based on the common questions in teaching Jingluo Shuxue Xue (Science of Meridian and Acupoint), the concepts and characters of PBT and the team oriented learning method were analyzed. The implementation steps of PBT were set up in reference to the team oriented learning method. By quoting the original text in Beiji Qianjin Yaofang (Essential recipes for emergent use worth a thousand gold), the case analysis on "the thirteen devil points" was established with PBT.

As a new biotechnology, protein transduction connects the target fragment with biology active and protein transduction domain, and transducer it in to cells, exert its biological effects. Protein transduc-tion domain is a small molecule peptide, not only the protein transduction domain can penetrate through cell membrane, but could maintain the activity of its fusion protein. Protein transduction is an emerging biology technology, it has been applied into all aspects of cell gene regulation since its invention. In this article, we take Tat, Pdx-1 and Beta/NeuroD for instance and review the application of transduction protein in the dif-ferentiation of pancreatic stem cell.

The anatomical and functional details of the anterior cruciate ligament (ACL) of the knee joint were studied on 55 normal cadaver knees of adults.ACL is made up of multiple fascicles, the basic unit of which is collagen. It is attached to the medial surface of the lateral femoral condyle and front of the anterior tibial spine. ACL is narrow in the middle and fans out at the attachments. The fascicles of ACL have been summarily divided into two groups: the anterior medial portion (AMP) and the posterior lateral portion(PLP). The tension of AMP is different from that of PLP during movement of the knee. ACL restricts the anterior drawer sign, and the internal and external rotation of the knee. AMP acts with the knee in flexion and PLP in extension. ACL restricts hyperextension, too. The function of ACL is related to its morpholcgical structure and the anatomy of the attachments. Rupture of ACL may result in instability of the knee, and injuries to the different components of ACL may produce different signs.

Objective To investigate the predictive value of ADC value in grading of neuroepithelial tumors. Methods The clinical data and images of 70 patients with neuroepithelial tumors pathologically proven were collected and analyzed restrospectively. All the patients were classified into low(WHOⅠ or Ⅱ)and high(WHO Ⅲ or Ⅳ)grade groups which included 40 and 30 cases respectively accroding to the 2007 WHO classification of tumours of the central nervous system. All the patients underwent plain and contrast-enhanced MR scan and DWI before surgery. The minimum ADC(MinADC)value was measured postoperatively on ADC maps. The Ki-67 labeling index(Ki-67 LI)of tumor tissue was determined by immunohistochemistry.MinADC values for two groups were analyzed using student t test, while the age and Ki-67 LI for the two groups was analyzed using Mann-Whitney test(P＜0.05 considered to be significant＝.Also the MinADC valHe and Ki-67 LI were analyzed with Pearson correlation. The receiver operating characteristic analysis was used for evaluation for grading neuroepithelial tumors of the patients using MinADC. Results The mean MinADC value[(1.08±0.31)×10~(-3) mm~2/s]of the low grade group was significantly higher than that[(0.74±0.18)×10~(-3) mm~2/s]of the high grade group(t=5.42,P＜0.05＝,and the Ki-67 LI of the low grade group[0-50%,median 4%]was significantly lower than that[0-75%,median 25%]of the high grade group(U=325.50,P＜0.05＝.There was a negative correlation between MinADC value and Ki-67 LI(r=-0.30,P＜0.05＝.The area under the ROC curve was 0.85,and the cutoff MinADC value of 0.86×10~(-3) mm~2/s for the differentiation between high and low grade neuroepithelial tumors provided the best combination of sensitivity(90.0%)and specificity(77.5%)(receiver operatingcharacteristic analysis).Conclusion MinADC value is helpful for prediction of neuroepithelial tumor grade.

Spine metastasis stereotactic body radiation therapy delivers conformal high radiation dose to the tumor target, and steep falloff dose gradients protect adjacent normal structures, especially spinal cord. Some studies demonstrated stereotactic body radiation therapy for metastatic tumors of the spine is safe and clinically effective. This technique markedly improved local control with an excellent symptomatic response compared with conventional external beam radiation therapy techniques, and is beginning to change the treatment paradigms for metastatic spine disease both as post-operative adjuvant therapy and primary definitive local treatment. Although the technique is being increasingly used in clinical practice, the optimal fractionation schedule remains uncertain. Based on the research of radiobiologic principles, radiological physics and clinical data, multiple session stereotactic body radiation therapy has some advantage in clinic.
